Hi folks - I was recently given an AW1600 that was going unused, but when it is powered on the screen just flashes. No Yammy logo, or anything. Anyone come across this, or have any ideas where I might want to start? Machine is surplus to my needs, but I'm hoping to get it functional for a student.

When a system like the AW1600 behaves erratically the first thing I do is unplug it from power, let it alone for some time, reconnect and retry. But given the fact you obtained it in the state it is in, this will probably be of no help.

You could try an update of the software. On the docs page ( <<-- click ) of our website you can find the file. It's a zip file that includes the instructions.

Hope this helps. The AW16G and AW1600 are great machines. I've had mine for over 11 years now and still works 100%.

Some others may come along and have additional ideas. Keep us posted!

So that points in the direction of the power unit. A simple voltage meter will tell you whether or not the unit gives a nice steady 16 V. Until you make sure, I would not try to use it for the AW1600 as it might damage the machine.

Does it still say 16 V (or a little bit lower, but a steady value) when the AW is connected to it?

Sometimes when a power supply is broken, it gets trouble controlling the voltage when the power supply has a load.

My AW16G power supply says 16V 2.4 A, which means it can handle a 6.6 ohm resistance. So you could load the power supply with a resistor of around 7 ohms and the voltage should drop just a little bit but maintain a steady value.

Giving this more thought... there might be a short circuit in the AW so the power supply gets overloaded. The above test should rule this out if it isn't the case.
